Stupid Ranked System

Stupid Ranked System

I get to 36 points in Silver 1 and go down to zero because of trolls on my team when I had a beyond positive score. Then I go up to 16. Then I go down to zero. I lose one more game and get bumped down to Silver 2 with 50 points. Are you kidding me? Go look at my match history. All positive. I never troll. Why is it fair that I get put into a group with complete idiots?
